The pregnant model -- who will welcome her and husband John Legend's second child, a boy, next month -- got a special surprise on Sunday morning when her daughter waddled into the room she was hanging out in.

Little Luna was all dressed up in a Tinkerbell outfit, smiling widely as she held a wrapped gift out in front of her. Upon entering the room, the toddler announced, "Happy Mother's Day!"

The Lip Sync Battle co-host couldn't help but coo over the precious sight, but since it was a little tough to hear Luna, she asked her daughter if she could say the phrase again.

"Oh, she said it!" she excitedly announced. "What did you say? 'Happy Mother's Day'?"

Luna's response? What Teigen called on Twitter a "blank stare," though the proud mom could be heard happily laughing throughout the video.

The 39-year-old singer also posted a very sweet message to Teigen to celebrate the holiday, as well as a sweet Instagram Story video where he showed off pictures of Luna with her grandmother and great-grandmother, wishing all the ladies in his life a happy day.

"Happy Mother's Day to my wonderful wife Chrissy. I see so much of you in Luna and I love it so much," he wrote. "I can't wait to meet our little boy and to see you give him so much love and get so much love in return. I'm so happy to be on this journey with you."
